There has been an explosion of health care data breaches in the United States in recent years, a study out Tuesday says. Between 2010 and last year 176 million health records were breached, according to the medical journal JAMA. The research is based on reports that health care providers and insurance companies sent to US health authorities.
The number of hacked files jumped in 2015, increasing cumulatively from 3.3 million in 2014 to 115 million the following year and peaking at 132 million in 2017 (cumulative since 2010), according to the study. Other types of breaches include the loss or theft of paper or film documents, and laptop files.
Network servers and emails are the principal weak links. While health care providers represent the largest number of breaches, the vast majority of the breached records are from health care insurers, where most of the data is concentrated.
